ASSEMB LING-MAGHINE Specification of Letters Patent.

Patented July 21, 1908.

Application filed October 20, 1905. Serial No. 283,660;

To all whom it may concern.- Be it known that I, ORRELL ASHTON, a citizen of the United States, residing at Lawrence, in the county of Essex and Commonwealth of Massachusetts, have invented oertain Im rovements in Assembling-Machines, of'whicli the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in, the sev eral figures. This invention relates to assemblin machines-for use in the manufacture of Toots and shoes, and more particularly to machines for facilitating the assembling of arts of bootsand shoes preliminary to pulling over and lasting.

Here-tofore, in "and shoes, so far as I am aware, no provision 50' has been-made for insurin that parts such as a counter, innersole and, ined up er will be assembled in proper relation for t e pullingover'opei'ation. 'It is-desirable that these parts 'b'esecured together in a proper mannet, for vi f-they are assembled in an incorrect relationit may be difficult or impossible to cure the defect in subsequent. operations.

My'invention is concerned moreparticu-j larl :the provision of-mean's for facilisotat m assembling of parts, such as these,

' ment oned, 'i'nfa correct relation.- It is .par-

fiailarlydesirable in? assembling these parts the ureanta; andup fiinnersole. a An important feature of the in'w-mtionconsists in'means for forcing upper and counter againstthe end of the innersole and for holdthe'm close contact therewith while thely are being secured to the innersole.

he machine herein described comprises a support for the parts to be assembled. Pref f erably,- the parts are assembled on? the last {5 u on which the boot or shoe is tmbelasted.

, I ave accordingly shOWilhe'iei FatIaSLsup port arranged to sustain a last in aifinver'ted the manufacture of boots r be held closely as L-treihe 'heel end "efore they aresecur'ed to the" projects thro h openl in, arranged to enter the heel of the last. he clamping mechanism is constructed to hold the-last from movement upon the pivot pin when brought into operative relation to thelast. I f

'Other features of the invention will be hereinafter described and defined in the claims. x, -.'-In the accoinpanyin drawings :'Figu1ie Tie a side elevation wit paifts in section...of a m'achine'constructed accordingto this invention. Fig. 2 is a plan of Fig. 1 with the last removed fromits support, andF-ig. 3 is a longitudinal vertical: section of a po'rtion of themachine illustrated inF'gs, 1and 2 show 7, ing theparts in operative position A, suitable standard 1 'is rovided' to ou port the last in ho'rizonta position. T e standard is fitted with alast pin 2 which enters'the usual pinhole in the heel art of the last, and'thus'pivotally sup orts t e last. U on the base 3, which forms '0 e lower 'pant o the standard-1,- upw'ardly projecting lugs-4 are provided which are perforated to receive: andsupport rotatabl-y-a-shaft 5. The shaft '5 5 carries a sleeve 6, placed between the up vwardly rejecting lugs 4 and firmly'attache'd to thes aft in any suitable way. The sleeve 6 is provided with arms --7 and 8, the arm 7 'being'conne'cted with, a-t'readle 10 by a'chain 9 or its equivalent while the arm 8 carries -'a Work engaging' deviceforming an importantfeature of the invention.- f 7 I T v The work-engagingdevice 'hi-ch' is illus trated comprises a clamping member 11 'carried on the u per end ,of the arm 8. The acting face 0 "the memberj l I- 'is preferably curved'as'shown inFig."2',-'soas"to embrace the heel end of the last. In the movement of the member 'IL-against the last, the concave face of said member tends to center the heel end of thellast with relation to said face and the engagement of said concave face with the last holds the last from swinging about the pivot pin 2.- A convenient .meansfor-10o supporting the member, 11 on the arm 8 compnses a slotted bar 12 atljustably held on the upper and of arm 8 by a set screw 13 The 0 am ing member 11 is pivotally carried on the s otted bar 12-by-a headed bolt-14 which 105 ngs ln-the clamping member 11 an bar 12 and is supp ied a a nut 16. The opening in the bar n which the bolt 14 is inserted me" be interior-l9 threaded if desired, so thatt a bolt 14 may no be screwed into position, the nut 15 serving as a lock-nut to retain said bolt in the position to which it is adjusted. The member 11 is supported with its acting face in position to engage the work when the arm 8 is swung towards the las and the movement of said arm is limited y contact of said member with the work. To hold the member 11 in position a fiat headed plunger 16 may be rovided which is held against a flattened face on the member 11 by a spring 17. It will be seen that in the arrangement shown the plunger 16 tends to hold the member 11 with its acting face in approximately correct position to bear on the work when said member is moved towards the last. It will also be seen that the member 11 is yieldingly controlled so that when forced against the work it may automatically move about its pivot as indicated in Fig. 3, to assume that position in which it bears evenly on the work. To move the clamping member away from the work means may be provided tending to hold the arm 8 in the positionshown in Fig. 1. The means shown comprise a coiled spring 18 surrounding the shaft 5, and connected at one of its ends to any fixed part of the machine, as for example one of the lu s 4 which carry the shaft 5. The other en of the spring may be attached to a rin 19 which is adjustably held on the shaft 5, y a set screw 20. By the adjustment of the ring 19 the inactive position of the armS may be varied. I

In the preferred mode of use of the machine shown, a counter 24 is inserted between lining 22 and u per 21 and arranged approximatel centrally of the heel. A last is placed wit 'n the lined upper and supported upon the in 2, in an inverted position. An innerso e 23 is placed loosely u on the last, with its heel edge between the ast and the lining. The-parts being in substantially the position shown in Fig. 1, the clam ing member 11 is brought against the wor forcing upper and counter closel against the edge of the innersole, and holding them in that position while a tack 25 is driven through upper, counter, lining and innersole preferably at the extreme rear of the heel.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is l. A machine for assembling parts of boots and shoes preliminary to lasting, comprising a last ivot arranged to support a last normally or free pivotal movement in an approximately horizontal plane, and clamping mechanism arranged to hold the rapper against the last at the heel and to hol the last simultaneously from movement upon said pivot.

2. A machine for assembling parts of boots and shoes preliminary to lasting, comprising a last ivot' arranged to support a last normally or free pivotal movement in an approximately horizontal plane, anda clamp sustained to be movable towards and from said pivot and having an acting face concave to receive the heel. end of the last, said clamp in its acting osition bein held from lateral movement w ereby said last is rigidly held upon its pivot.

3. A machine for assembling parts of boots and shoes preliminary to lasting, comprising a stationary last pivot arranged to support a last normally for ree pivotal movement in an approximately horizontal plane, and clamping mechanism arranged to hold the upper against the last at the heel and to hold the last simultaneously from movement upon said pivot.

4. An assemblin machine, comprising a stationary vertical last pin, arranged to su port a last pivotally in an approximatey orizontal position, an arm pivotally supported to move in a vertical plane, a clamp carried by said arm, means tending to hold said arm in a position removed from the last pin, and mechanism for actuating said arm to hold the clamp against the last supported upon the last pin.

5. A machine for assembling parts of boots and shoes reliminary to lasting, comprising a vertical ast pivot arranged to support a last normally for free pivotal movement, a clamp sustaining member arranged for movement toward and from said last pivot, and a clamp having a rigid work enga mg face and arran ed for free movement a out a horizonta axis upon said member.

6. A machine for assembling parts of boots and shoes reliminary to lasting, comprising a vertical ast pivot arranged to support a last normally for free pivotal movement, a clamp sustaining member arranged for movement toward and from said last pivot, a clamp having a rigid work enga ing face and arran ed for free movement a out a horizonta axis upon said member, and means for maintaining the clamp normally in a predetermined position upon said member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
